This paper aims to diagnose the strategy execution ability and to provide corresponding measures for Korean oceanic shipping companies. The analysis method is the t-test between importance awareness and Corresponding ability for strategy execution diagnosis index(XPP). According to the diagnosed results, the strategy development is unsatisfactory because the strategy implemented does not adhere to concurrent environmental change. Moreover, the execution of the strategy is also unsatisfactory. Therefore, an evaluation shows that there is a need for a SWOT analysis using BSC, an organization structure to strengthen the strategy execution ability and the support from the market condition analysis prediction center.

Improvement is required to solve problems depending on long term use of signal equipment in the existing city railroad and to raise quality of passenger services. Accordingly, for more efficient improvement, we examined the procedure of executing construction of the communication based train control system in Korean city railroads, which is globally studied. The procedure of executing construction of the system is to present a plan for construction first of ail and then to prepare a strategy for construction of the system. It is required to establish a procedure for execution in each step depending on the prepared strategy and then to establish a detailed execution plan. We studied such an execution procedure, divided the execution procedure for application of the train control system through five steps to prepare the execution procedure.

The objectives of this study is to develop a strategy for the adoption of BPM(Business Process Management) standards and an implementation guideline of the BPM standard for BPM solution developers focusing on BPEL(Business Process Execution Language) which is regarded as the most important BPM standard. In the heterogeneous and distributed IT environments, every type of enterprise software requires standards to enhance interoperability. BPMS(Business Process Management System), which is a type of enterprise software requires BPM standards such as BPEL(Business Process Execution Language), BPMN(Business Process Modeling and Notation), BPQL(Business Process Query Language) and so on to achieve multi-system interoperability and component interoperability with their BPM solutions. It is quite helpful to provide the adoption strategy concerning BPM standards for each type of BPM solution vendors who need the BPM standards. Since the BPEL is conceived as the most important BPM standard and widely adopted by many BPM vendors, we have proposed a reference architecture for BPEL implementation and also developed the detail implementation guideline of core components of the BPM system supporting the BPEL standard. Using the strategy and implementation guideline proposed in this work, BPM solution vendors can establish their own standard adoption strategy and they can also develop their BPM solutions supporting the BPM standards more efficiently.

MapReduce (MRV1), a popular programming model, proposed by Google, has been well used to process large datasets in Hadoop, an open source cloud platform. Its new version MapReduce 2.0 (MRV2) developed along with the emerging of Yarn has achieved obvious improvement over MRV1. However, MRV2 suffers from long finishing time on certain types of jobs. Speculative Execution (SE) has been presented as an approach to the problem above by backing up those delayed jobs from low-performance machines to higher ones. In this paper, an adaptive SE strategy (ASE) is presented in Hadoop-2.6.0. Experiment results have depicted that the ASE duplicates tasks according to real-time resources usage among work nodes in a cloud. In addition, the performance of MRV2 is largely improved using the ASE strategy on job execution time and resource consumption, whether in a multi-job environment.

At NOW (Networks Of Workstations), the load sharing is very important role for improving the performance. The known load sharing strategy is fixed-granularity, variable-granularity and adaptive-granularity. The variable-granularity algorithm is sensitive to the various parameters. But Send algorithm, which implements the fixed-granularity strategy, is robust to task granularity. And the performance difference between Send and variable-granularity algorithm is not substantial. But, in Send algorithm, the computing time and the communication time are not overlapped. Therefore, long latency time at the network has influence on the execution time of the parallel program. In this paper, we propose the preSend algorithm. In the preSend algorithm, the master node can send the data to the slave nodes in advance without the waiting for partial results from the slaves. As the master node sent the next data to the slaves in advance, the slave nodes can process the data without the idle time. As stated above, the preSend algorithm can overlap the computing time and the communication time. Therefore we reduce the influence of the long latency time at the network and the execution time of the parallel program on the NOW. To compare the execution time of two algorithms, we use the $320{\times}320$ matrix multiplication. The comparison results of execution times show that the preSend algorithm has the shorter execution time than the Send algorithm.

본 논문에서는 그리드 환경을 구축할 때 자원 비용 면에서 효율적인 스케줄링 정책을 제안한다. 이 스케줄링 정책은 로컬 컴퓨팅 자원을 효율적으로 할당하기 위해 자원 비용과 작업 실패율을 고려한다. 이 스케줄링 정책의 특징은 원격 스케줄러와 로컬 스케줄러를 사용하여 2단계 스케줄링을 수행한다. 원격 스케줄러에서는 자원 데이터베이스에 저장된 네트워크와 로컬시스템의 정보를 사용하여 작업의 총실행시간이 최소인 로컬시스템을 선택하여 작업을 할당한다. 로컬 스케줄러에서는 할당된 작업의 대기시간과 처리시간을 재계산한 후, 작업을 데드라인 내에 처리할 수 있다면 로컬시스템에서 수행한다. 하지만 데드라인을 초과하면 다른 로컬시스템으로 이주시켜 처리함으로써 작업 실패율과 자원 비용을 최소화한다. 제안한 스케줄링 정책은 기존 Greedy 정책에 비해 작업 실패율은 높지만, 자원 비용을 줄이는 면에서 더 우수함을 보인다. 본 논문에서는 시뮬레이션을 통하여 제안한 스케줄링 정책이 기존 Greedy 스케줄링 정책에 비해 컴퓨팅 자원 비용을 줄이는 면에서 효과적임을 보인다.
